  • Managing copying of data in storage systems
    Patent number: 9891860
    Abstract: A method is used in managing copying of data in storage systems. A request is received to copy a portion of a source logical object to a target logical object. The source and target logical objects are subject to a deduplicating technique. The portion of the source logical object is copied to the target logical object by updating metadata of the target logical object.

  • Coalescing transactional same-block writes for virtual block maps
    Patent number: 9430503
    Abstract: A technique for preserving metadata changes in a transaction log involves coalescing metadata changes based on the block of storage in which the metadata to be changed resides. Metadata change information that accompanies a file system command is stored in nodes of a searchable data structure, wherein each node accumulates metadata changes for a respective block of storage. Once all metadata changes are specified in the searchable data structure, or after some threshold number of metadata changes have been stored, the storage processor composes a transaction for each node summarizing the metadata changes and writes the transaction to the transaction log.
